Your fee is considerably lower than the typical fees needed for a transaction to confirm. If you wanted to resend it, you would likely need to perform either a CPFP transaction (if there are sufficient funds sent to a change address you control), or double-spend (by taking Electrum offline, creating a new transaction with the same inputs as the stuck one and a considerably higher fee, signing it, and broadcasting it using a tool like bx or a node that hasn't seen your original transaction)

The thing is this transaction fee is higher than my usual! It's about $90. Is that nowhere near enough? I also don't know how to do the two things you suggested. I will check the service link you sent. Is there no way to let this transaction through and I will always go higher in future. best regards
